MORTAR-SPHEADlNG MAOHlNI I.

Specification of Letters Patent.

Patented may 8, 1986.

Application filed October 2, 1905- sm'ifll NO 331 014- To all whom it may concern.-

Be it known that I, CHARLES W. FERTICK, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Mortar Spreading Machines, of which the following is a specification.

My invention relates to an improvement in plastering-machines, the object being to )10- vide an apparatus sulliciently light to ma c it easily movable for ap lying plaster either to a wall or ceiling; and it consists in certain novel features of construction and combinations of parts which will hereinafter be de scribed, and pointed out in the claims.

In theaccompanying drawings, Figure 1 is a. longitudinal sectional view. Fig. 2 isetn end view. Fig. 3 is a lan view with a portion broken away, an Fig. 4 is a fragmentary view of a slightly-modified form for use in applying plaster to the wall.

A represents the frame of the machine, which may rest directly upon the floor or on rollers or casters, so that it may be easily moved into different positions on the floor.

B is a stand-pipe which is adapted to receive the mortar from a spout 1, into which the mortar is fed. A screw conveyor 2 in the stand-pipe conveys the mortar upward to the flange-pipe 3, through which it passes to the hopper 4, and in this hopper 4 a plasteringscrew 5 turns. This plasterin -screw is like the convcyenscrew 2 except t at it projects above the hopper to form a trowel 6 for spreadin plaster or cement upon the ceiling.

stub-s aft 7 extends downwardly from the stem of screw 5 and is provided with a gear 8, which meshes with gear 9, which latter is keyed to slide on the vertical shaft 10, it being held in adjustable osition by the setscrew a, and this vertical shal't is provided with a. beveled pinion 11 which meshes with beveled pinion 12 on the driveshaft 13, and through the latter motion is communicated to the screw 5. Likewise shaft 16 is provided with a gcanwheel 14, which meshes with gear-wheel 15 on the lower end of conveyor-screw 2. Screws 19 and 20 are stopped at their lower ends in the frame, and they arc threaded at their upper ends to raise and lower the hopper 4. Screws 17 and 18 on these screws 19 and 20, res ectively, intermesh with each other, and a and-whcelC on i one of these screws is turned to raise and lower the hopper. A sleeve 21 is fitted around the stand-pi e B, and the stand-pipe is rovidcd with a pliirality of holes 22 22 at di erent elevations, an one of which is adapted to register with the ranch pipe 3, the entire sleeve 21 and branch pipe moving with the ho per 4.

In tie construction shown in Fig. 4 the hopper 4, as well as the screw 5, extends horicont-ally for plasterin a wall, and a beveled gear 22 being secure in position bya setscrew 23, winch engages a pinion 24 on the stem of the screw 5. The hopper 4 is removable from the stand-pipe B, so that either form may be used, and for that reason the shaft 10 is equipped with two gear-wheels 9 and 22.

Slight changes might be resorted to in the form and arrangement of the several parts described without departing from the s hit and scope of my invention, and hence do not wish to limit In self to the exact construction herein set fort i; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is 1 1. In a plastering-machine, the combination with a ho per and means for supplying the hopper, o a conveyor screwed therein, said screw te minating at its outer end in a plasteringtrowcl.

2. In a plastering-machine, the combination with a frame and stand-pipe and feedspout of an adjustable hopper, a conveyorscrew in the stand- )ipe and hopper and means for turning said screw, the screw in the hopper terminating in a plastering device.

3. The combination with a suitable frame and stand-pipe having a plurality of holes therein, of a convever screwed in the standpipe, a sleeve fitted to the stand-pipe, a hop- 7 er abranch i eextendin from the hopper P [P P g and removal) y connected with the sleeve, a conveyor screwed in the hopper terminating in a plastering-trowel at its outer end, and means for raising and lowering the hopper slid revolving the screws. 1
